What do %/% and %% mean?
dplyr, r
Solution
From the `?"%%"` help page
`%%` indicates x mod y and `%/%` indicates integer division. It is guaranteed that `x == (x %% y) + y * ( x %/% y )` (up to rounding error) unless y == 0 where the result of `%%` is NA_integer_ or NaN (depending on the typeof of the arguments).
Problem
I've recently seen code like this: ``` library(dplyr) mtcars %.% mutate(carb_10 = carb %/% 10) ``` And this.... ``` mtcars %.% mutate(carb_10 = carb %% 10) ``` Can anyone explain what %/% and %% do in above code?
